The uPrint printer in my office uses proprietary software that I haven't had time to set up or learn, and it takes quite a while for the heated chamber and bed to heat, so it's not good for a quick print anyway. I am hoping the simple Ender will be usable by my kids and that they'll 'graduate' to the pro machine in time.<br /><br />Keep up the effort, and glad your hand is healing.<br /><br />nNick Flandreyhttps://www.blogger.com/profile/13019834912388638989noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-42049437677666518102021-10-11T21:18:13.644-04:002021-10-11T21:18:13.644-04:00Using cut (not torn, this deforms the paper backin...Using cut (not torn, this deforms the paper backing) sandpaper strips for rotating parts tends to work better than the stick method. Switching to the abrasive plastic scrubbie pads (cut in strips) for final finish works well. Paint/bodywork supplies for those pads, as the ones in cleaning supplies tend not to be good enough on metal.Willhttps://www.blogger.com/profile/00722792638246578812noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-68277074358786341132021-10-11T07:40:11.788-04:002021-10-11T07:40:11.788-04:00That's kind of self correcting.

I kept it moving side to side to keep it wearing evenly and moved it front and back to keep fresher paper on it. It can go a few inches in toward the work and back.SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-62367376827394221282021-10-11T01:33:57.723-04:002021-10-11T01:33:57.723-04:00Looks like if the sanding stick is not dead square...Looks like if the sanding stick is not dead square to the axis, the shoulder of the eccentric rectangular barstock could hit it on rotation? ravennoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-57697546198246536432021-10-10T21:26:08.893-04:002021-10-10T21:26:08.893-04:00I don't see why it needs to be dead square.

People tear off strips and just wrap a loop around the rotating work to sand to uniform diameter.<br /><br />In this case, I used the three sanding sticks. The first one that was too wide with 220 grit, the assembled one with 400 and the last one with 1000. The smallest diameter is .3751 and largest is .3752, by my micrometer. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-54991899673805785682021-10-10T21:22:30.672-04:002021-10-10T21:22:30.672-04:00That's too much like the old, "mill at wi...That's too much like the old, "mill at will, file to fit."

Tongue depressors might be harder to find retail.<br /><br />I agree low-end 3D printing is disappointing, but on the other hand, laser cutters! Kerf on acrylic (PMMA, Plexiglas, Lucite, Perspex) is narrow enough the pieces almost re-weld. Cut 1/4" plywood for dovetailed boxes with detailed graphics. Cut cardboard for cradle inserts for shipping fragile items. Mark acrylic by less heat giving a sandplasted etched look, or removing black spray paint from back surface. Mark aluminum by bleaching anodizing dye. Mark stainless steel by laser over spray moly lubricant.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-84675248424595224732021-10-10T01:57:40.404-04:002021-10-10T01:57:40.404-04:00A popsicle stick with sandpaper glued to it?

The potential is there, with better motors, better hot-ends, better everything, but for consumer grade stuff, the market is still dealing with Model-T level of engineering when it should be at the fuel-injection era level of engineering.<br /><br />The jump from 'consumer grade' to 'commercial grade' is huge, expensive and deals with proprietary everything so the average 3D monkey can't futz things up by changing out thingamajigs and doohickeys.<br /><br />And the price difference between 'consumer grade stuck in whatever hell was 15 years ago' and 'professional grade monkey keeps hands off of the pieces parts' is ridiculous.<br /><br />Oh, well.<br /><br />I've watched as others have had 'fun' with 3D, then gotten annoyed, then done the hot-rodding thingy and gotten even more frustrating, and then just sold everything at a loss and gone back to standard machine shopping. For all the reasons you have above. No progress in equipment really, no new tech, no really new products or supplies or anything.<br /><br />Which sucks. Still an interesting technology, but...Beanshttps://www.blogger.com/profile/15293778848879361153noreply@blogger.com
